RAILWAY-CAR-DOOB ARRANGEMENT.

Application filed October 23, 1919. Serial No. eaaeas.

To all whom it may concern Be it known that I, HARRY S. HART, a citizenof the United States, residing at Chicago, in the county of Cook andState of lllinois, have invented certain new and useful Improvements inRailway-Car-Door Arrangements, of which the following is aspecification.

This invention relates to railway cars, and more particularly to doorarrangements therefor. I

Car doors such as the dump doors for general service cars have to betaken off and put on relatively frequently as a result of necessaryrepairs. Heretofore these dump doors have been hinged in rather apermanent manner so that considerable time and eifort are required toput on and take oif such doors.

Accordingly, one object of my invention is to provide a simple andefficient arrange-- ment whereby dump doors may be put on and taken ofiwith great rapidity and ease.

Another object is to provide a simple demountable hinge arrangement fordump doors.

These and other objects are accomplished bymeans of the arrangementdisclosed on the accompanying sheet of drawings, in which Figure 1 is atransverse sectional view of a general service car embodying myinvention; and Figure 2 is a detail view of the hinge construction ofthe door.

This general service car includes sides 10, ends 11 and a floor composedlargely of doors 12, which are hinged at their inner edges to the centersill structure 13. The car includes transverse frame members 14- provided with slots '15, in which shafts 16 are laterally movable. Theseshafts when located at the inner ends of the slots and underlying the.doors 12 act as supports for the latter.

It will be understood that when the shafts are moved outwardly to theouter limits of the slots 15, the doors are free to drop into an openposition. The doors 12 are support-- ed in open position by suitablestop members 17 supported by the cross frame members let.

This invention has to do primarily with the doors 12 and moreparticularly with the mounting therefor. These dump doors 12 are.relatively heavy and accordingly rather dillicult to handle. Mountingthese relatively heavy dump doors on hinges in the old manner takesconsiderable time and offort and, as pointed out hereinabove, it isadvantageous to be able to rapidly mount and dismount such dump doorswith respect to their hangings.

I have provided a readily demountable arrangement in which pivot pins ormembers 18 are provided and as here shown are associated with the centersill structure 13. Each of the doors is provided with a plurality ofhinge members 19 which are in the form of open hooks 20, which book overand pivot around the pivot members 18. The hook portion 20 of the hingemember extends through a. large enough arc to prevent the door frombecoming accidentally disengaged from its mounting, but at the same timeis just embracive enough in its action with respect to the pivot pins 18to make it possible readily to disengage the hinge member 19 formounting and demounting the door.

It will be understood, of course, that the door cannot be demounted whenin its closed or horizontal position, as shown at the left hand side ofthe figure. This door is mounted and demounted when in open position, asshown at the right hand side of the figure. To mount and demount thedoor, it is merely necessary to pivot the same about the stop member 17,as shown at the right hand side of the figure, whereby the open hookedportion 20 may be elevated above the pivot member 18 and then eitherforced over the pin to secure the door in place or withdrawn from thepivot member 18 for demounting the door. The mounting and demountingaction may be done with great rapidity and It will be noted that thedoor is mounted by applying the hook over the pivot member and thenpermitting the hook to lower, said door being demounted by raising thehook from the pivot member and then moving the door outward away fromthe center sill. It will also be noted that the doors may be mounted anddemounted without disturbing the position. of the pivot pin. Attentionalso is called to the fact that the doors are wholly free from the dooroperating eflieient manner and in a minimum amount of time, and at thesame time independent of any interference with the door operatingmechanism. v

It is my intention to cover all modifications of the invention fallingwithin the spirit and scope of the following claims.

I claim: I

1. In a general service car,;a rigid car member, a fixed pivot memberlocated adjacent thereto, a door, said door'having a hinge memberadapted to be removably associated with the pivot member,- clearancesbetween the several. being such that the hinge-may be removedfrom thepivot only when the door is in the open position 2. In a general servicecar, a rigid ear member, a fixed pivot memberulocated adjacent thereto,adoor, saiddoorhaving a the members hinge member adapted to be removablyassociated with thepivot member, the clearances between the doorandrigid car member being such that the hinge may be removed from thepivot only when the door is in the open position."

3. In a general service car, a rigid ear member, a fixed pivot memberlocated 'adjacen-tnthereto, a door, said door having a V hinge member inthe form of an open book o for embracing aportion of said pivot memf herand being removable therefrom when the door is open,-the clearancesbetween the door and rigid car member being such as to prevent suchremoval when the door is closed.
